Hunger-related intrusive thoughts reflect increased accessibility of food items

The elaborated intrusion model (Kavanagh, Andrade, & May, 2005) argues that a craving episode begins with a desire-related intrusive thought. This study tests the assumption that such intrusive thoughts, during hunger, reflect an increase in accessibility of food-related information in memory. Fifty-six undergraduates were randomly assigned to hungry or satiated conditions. Hunger was manipulated by asking the “hungry” group to abstain from eating breakfast and snacks prior to testing before lunch, while the “satiated” group was asked to eat normally and attend testing after lunch. Participants completed a lexical decision task containing food-related and neutral words, an intrusive thoughts questionnaire and a hunger questionnaire. Priming for food-related items relative to neutral on the lexical decision task was higher for hungry participants than satiated participants. Priming correlated strongly with frequency of food-related intrusive thoughts during the task. We conclude that desire-related lexical decision priming could provide a useful objective correlate of proneness to desire-related intrusions.     

Priming and timing: a test of two perspectives

Supporting a ‘stage’ perspective of assimilation and contrast effects, and in contrast to an ‘extremity’ conceptualization, this study demonstrated that priming moderate person exemplars before the behaviour of an ambiguous target person had been encoded results in assimilation, whereas priming such exemplars after encoding results in a small contrast effect. © 1998 John Wiley & Sons, Ltd.     

非自主闯入焦虑发生的机制：阈下启动效应的实验研究

本研究采用阈下情感启动范式, 研究威胁信息启动效应及其特质焦虑的调节作用,旨在揭示焦虑非自主闯入性特点形成的机制。实验在随机的三种条件下（阈上/阈下/基线）给38名被试呈现两种目标词（威胁词和中性词）,其中基线条件不呈现目标词;之后要求被试在回避目标词的条件下完成组词任务,结果：（1）无论是中性词还是威胁词,被试阈下条件下目标词的击中率显著高于基线条件;（2）特质焦虑对阈下启动效应起着调节作用：高焦虑组被试威胁词的启动效应显著高于中性词,低焦虑组被试中性词的启动效应显著高于威胁词。结论：阈下启动效应显著,高特质焦虑组个体对威胁信息的无意识加工会增强对威胁信息的意识加工,产生闯入性想法,导致焦虑非自主闯入性的特点。     

Student driver propensity to engage with distractions – a self-report survey

This paper reports a survey of engagement with, and ratings of, driver distraction, for undergraduate student drivers. Survey data was collected using an anonymous online questionnaire. 530 respondents contributed to the survey during a seven-year data collection period.Results indicate that the three internal-to-vehicle behaviours rated as most distracting when driving were ‘writing text messages’, ‘internet use’, and ‘reading text messages’. The three most frequently undertaken distractions were, ‘(interactions with) adults’, ‘daydreaming’, and ‘eating, drinking or smoking’. Considering external-to-vehicle distractions, the top three rated were ‘environmental conditions’, ‘unexpected objects or events’, and ‘animals behaving unexpectedly’; while the most frequently experienced external distractions were ‘people (behaving normally), ‘busy roads’ and ‘official signage’. Some evidence was found that internal-to-vehicle distractions were relatively more distracting than external-to-vehicle ones, along with limited findings showing significant variation in the amount of engagement with distractions over time. Significant predictive models for engagement with distraction were calculated (for both work-related and non-work-related driving) and found to be broadly in agreement with previous research, although accounting for less variance in the models. Significantly greater engagement with distractions was found during non-work-related driving, when compared to work-related.The data present a picture of ongoing and substantial engagement with distracting behaviours for this population over the data collection period. For example, on a daily or weekly basis, more than three-fifths of respondents reported willingness to read text messages with the vehicle in motion; while just under half indicated that they typically write text messages in the same circumstances. However, the findings do offer some promise that interventions targeted towards non-work-related driving behaviours may be effective to reduce volitional engagement with distractions.     

Resistance to satiation of consummatory and instrumental performance

In three experiments rats received training in a straight alley under high hunger and then were tested satiated. Both eating and running continued to occur under satiation, but the two responses were not completely correlated, and continued running did not depend upon continued eating. Further, groups differed in their eating behavior, although all experienced the same satiation procedure, suggesting that eating under satiation is not just a reflection of incomplete satiation. Resistance to satiation of the running response was greater following partial reward than following consistant reward and tended to be greater following small reward training than large reward training, regardless of schedule of reward. Eating during satiation was greater following partial than following consistent reward and was greater if the same reward magnitude was given in satiation as in acquisition than if a different reward magnitude was given. It was suggested that resistance to satiation is an associative phenomenon. Eating and running occur during satiation because the stimuli present during satiation continue to elicit them. The differences between results using rewarded satiation and results using high drive extinction as measures of persistence were attributed to satiation being nonfrustrating.     

死亡凸显对自我姓名注意瞬脱对抗效应的影响

已有研究表明死亡凸显会抑制自我面孔和自我参照记忆加工的自我优势,可是死亡凸显对自我姓名的影响尚不明确,本研究采用事件相关电位技术,探索死亡凸显对自我姓名注意瞬脱对抗效应及其大脑神经活动的影响。58名被试在经历不同的启动任务后,完成自我姓名、朋友姓名和名人姓名的注意瞬脱任务。行为结果发现自我姓名识别正确率显著高于朋友姓名和名人姓名,表现出稳定的自我姓名加工的注意瞬脱对抗效应;电生理数据发现死亡启动后自我姓名诱发的P300波幅显著低于消极启动组和中性启动组,而朋友姓名和名人姓名并不受启动的影响。本研究结果与以往研究结果共同表明死亡想法凸显会使个体将抑制自我加工（自我姓名、自我面孔和自我参照记忆）作为应对远端死亡焦虑的一种手段。     

友谊质量与青少年直觉进食：链式中介模型及性别差异

基于积极心理学, 采用友谊质量量表、自我怜悯量表、身体欣赏量表和直觉进食量表, 对2438名初中生进行调查, 并运用结构方程模型探讨友谊质量与青少年直觉进食的关系、作用机制及其性别差异。结果表明：(1)友谊质量与直觉进食呈显著正相关; (2)自我怜悯和积极身体意象在友谊质量与直觉进食间起中介作用, 且该中介作用包含三条路径：自我怜悯的单独中介作用、积极身体意象的单独中介作用以及自我怜悯-积极身体意象的链式中介作用; (3)中介效应性别差异仅出现在友谊质量与直觉进食(分维度)的关系中, 即“无条件地允许进食”和“进食不受情绪影响”两个维度。研究结果为促进青少年形成积极身体意象、健康饮食行为提供了参考建议和干预指导。     

Nutritional habits and motivations to eat after a palatable pre-load

A representative sample of college students was surveyed about nutritional habits and motivations to eat. Females were more likely to report dieting, being overweight, reading nutritional labels, eating healthy meals, as well as hungering for and consuming lower fat foods compared to males. Males reported a greater hunger for and consumption of candy bars compared to females. Thus, females may not be as ambivalent about eating sweet or higher fat foods as previously suggested. The experimental manipulation involved exposing subjects to either candy before the survey, candy with the survey, or just the survey with no candy exposure. Females exposed to the candy preload indicated an increased hunger for fruits and vegetables compared to female controls. Portions of this research have been presented at the 1999 annual meeting of the Eastern Psychological Association in Providence, RI. The authors would like to thank Mr. Steve Lukasik and Ms. Christie Piedmont for their assistance on this project.

Personal Theories of Hunger and Eating1

Recent research on hunger and eating has shown that (a) among individuals with adlibitum access to food, hunger and eating are not regulated by deviations in the body's energy resources from set-points, and (b) it is healthier for people to consume their daily caloric intake as several small snacks than as 3 large meals. People's beliefs about hunger and eating were assessed in 2 questionnaire studies. In Study 1, a large sample of undergraduates was surveyed; in Study 2, dietetics students, nursing students, medical students, dietitians, nurses, and doctors were surveyed. Both studies revealed that people's personal theories of hunger and eating were inconsistent with research findings in ways that could promote overconsumption. These results suggest that educational programs designed to modify the beliefs about hunger and eating of people suffering from problems of overconsumption and of health professionals who treat problems of overconsumption may increase the effectiveness of current treatment regimens.     

自我概念威胁以及与重要他人的比较共同削弱自我面孔优势效应

内隐积极联想理论(implicit positive association, IPA)认为自我面孔识别以及与之伴随的自我意识激发了自我概念的积极属性, 促进了对自我面孔的识别优势, 因此通过自我概念威胁可以削弱自我面孔识别的优势效应。本研究旨在探讨自我概念威胁以及与重要他人的比较对自我面孔优势效应的共同影响。实验一为自我-朋友对比实验, 10对同性好友(20名被试)在接受完自我概念威胁启动或者非威胁性启动后对自我面孔和朋友面孔进行朝向的判断, 结果发现非威胁性启动后, 自我面孔的优势效应依然存在, 而在自我概念威胁启动后, 自我面孔优势效应消失。实验二为自我-陌生人对比实验, 另外20名被试在接受完自我概念威胁启动或者非威胁性启动后, 对自我面孔和陌生人面孔进行朝向的判断, 结果发现, 无论是自我概念威胁启动还是非威胁性启动后, 自我面孔识别优势效应都依然存在。两个实验的结果均主要体现在用左手进行反应的时候。结果表明：自我概念威胁以及与重要他人的比较共同削弱自我面孔优势效应; 而左手效应的发生似乎表明了大脑右半球对自我面孔识别的主导和调节作用。     

无意识自我控制目标启动对自我损耗的补偿效应

本研究基于对无意识目标启动的研究,采用阈上、阈下启动方式探讨无意识目标启动对自我损耗的补偿作用。实验1发现,阈上无意识目标启动能够有效提高自我控制,促进自控表现。实验2发现,阈下无意识目标启动对自我损耗存在补偿效应。上述结果提示,通过无意识启动方式激活自我控制目标,可以克服自我损耗的不良效应,且无需意识参与。     

The pull of the past: when do habits persist despite conflict with motives?

To identify the factors that disrupt and maintain habit performance, two field experiments tested the conditions under which people eat out of habit, leading them to resist motivational influences. Habitual popcorn eaters at a cinema were minimally influenced by their hunger or how much they liked the food, and they ate equal amounts of stale and fresh popcorn. Yet, mechanisms of automaticity influenced habit performance: Participants ate out of habit, regardless of freshness, only when currently in the context associated with past performance (i.e., a cinema; Study 1) and only when eating in a way that allowed them to automatically execute the response cued by that context (i.e., eating with their dominant hand; Study 2). Across all conditions, participants with weaker cinema-popcorn-eating habits ate because of motivations such as liking for the popcorn. The findings reveal how habits resist conflicting motives and provide insight into promising mechanisms of habit change.     

Adults' versus children's performance on the Stroop task: Interference and facilitation

Stroop tasks (Stroop, 1935) present stimuli having two dimensions, and participants respond to one dimension whilst ignoring the other. The two dimensions are made congruent, incongruent or neutral with respect to one another. Many claim that ‘Stroop interference’ is higher in children than in adults. However, taking interference as the difference between the incongruent condition and the neutral condition, with interference within the congruent condition itself termed the ‘incongruity effect’ then surprisingly few studies directly address this issue. Also, there is recent debate as to whether the ‘facilitation effect’ (the contrast between the congruent and neutral conditions) is just the opposite of interference. The present investigation (N = 31) concerned a direct comparison between children and adults. Although the incongruity effect reduced with age, interference did not. However, facilitation was far higher in children than in adults. The groups' opposite facilitation/interference asymmetry was used to examine the recent claim that these derive from inadvertent word‐reading and suppression of semantic activation, respectively; rather than solely from the latter.     

Enhancing Young Infants’ Representations of Physical Events Through Improved Retrieval (Not Encoding) of Information

Infants’ representations of physical events are surprisingly flexible. Brief exposure to one event can immediately enhance infants’ representations of another event. The present experiments tested two potential mechanisms underlying this priming: enhanced encoding or improved retrieval. Five-month-olds saw a target block become hidden inside a container, followed by priming events that involved a second block. The target was subsequently withdrawn from the container. Infants noticed a change to the target’s height after seeing priming events involving occlusion, but they failed to so do if priming events involved no occlusion (Experiment 1). Infants noticed the change even when the priming and target blocks were not identical (Experiment 2). Because the target became fully hidden before the priming events started, priming must have arisen from improved retrieval, not enhanced encoding, of information about the target. The results add to our understanding of how brief observation of one event can affect infants’ processing of subsequent events, thereby elucidating fine-grained aspects of the representational process.     

Contagious bodies. An investigation of affective and discursive strategies in contemporary online activism

The paper presents an analysis of Climate Justice Fast, a campaign consisting of an international hunger strike against political in action on climate change. Within the theoretical framework of political online activism and theories of affect, we investigate the encoding and decoding of the starving activist bodies in relation to CJF. Our material consists of texts from the CJF website, activist blogs, and two online debates on a large Danish media platform. The methodological approach is discourse analytical and esthetic-affective. In our analysis we outline the different semantic significations of the starving bodies as central signifiers and we investigate the different affective responses to the hunger strike. We furthermore argue that the starved body seems to be relationally powerful, because of both its contagious ability to attune other bodies and its semantic ‘wildness’.     

Alcohol dependence,beliefs and the priming effect

Twenty hospitalized alcoholics served as their own controls in a study which sought to compare psychophysiological and cognitive factors as mediating influences on the priming effect of alcohol. Ten subjects were independently assessed by a psychiatrist as being severely dependent on alcohol and ten as mildly or moderately alcohol dependent. Physiological, behavioural and subjective indices of the motivation to drink alcohol were employed 15 and 60 min after subjects had consumed beverages on four separate occasions corresponding to four priming conditions. These priming drinks contained either 60 ml vodka in heavy dilution or just tonic water, and in each of these conditions subjects were either led to believe that the beverages contained alcohol or they had no alcohol. The severely-dependent group displayed a degree of concordance between the indices of motivation to drink, and the levels of these tended to be significantly higher than in the less-dependent subjects. The results suggest that severely alcohol-dependent subjects were more disposed to drink 60 min after consuming alcoholic drinks than after soft drinks, regardless of whether they believed that the priming drinks had contained alcohol. Cognitive factors assumed greater importance for the drinking behaviour of less-dependent subjects, although there was evidence of discordance across behavioural, physiological and subjective measures for this group.     

Cognitive models of stereotype change: (2) Perceptions of homogeneous and heterogeneous groups

The reported study compared change in stereotypic perceptions of homogeneous and heterogeneous groups, when subjects were presented with a pattern of stereotype-inconsistent information that was either concentrated in two extreme group members or dispersed across six members. Results pro vided some support for the ‘conversion’ model (in which stereotypes change in response to salient instances) in the case of a homogeneous group, where stereotypical responding was lower in concentrated than dispersed conditions. In the heterogeneous-group conditions, there was no effect of pattern. In addition, subjects' estimates of stereotype-consistent information were higher, and of inconsistent information were lower, and they perceived more members as typical, and fewer as atypical, when the target group was heterogeneous versus homogeneous. There was also support for the ‘subtyping’ model (in which disconfirming individuals are isolated from other group members) in the concentrated conditions. A theoretical account of these findings is given in terms of stereotype change via salience for homogeneous groups, and the need to integrate research on cognitive models of stereotype change and perceived group variability.     

Response-compatibility effects in children

The Eriksen Flanker task is a classic paradigm for investigating interference at the level of response compatibility. Several previous studies analyzed the ability of young children (starting at the age of four years) to ignore flanking distractors in children-specific variants of the task. However, in all published studies the interference took place at the perceptual level as well as on the level of response compatibility because the ‘compatible condition’ involved stimulus congruency as well as response compatibility. By confounding stimulus congruency and response compatibility, interference at the level of response programming and priming at the perceptual level cannot be distinguished: the observed flanker effects might not be the result of successfully ignoring but instead might just be explained due to priming. We tested 57 children aged between 7 and 12 years in a flanker variant in which all trials were perceptually incongruent but different at the level of response compatibility (compatible versus incompatible). Children showed a flanker effect (faster reaction times in response compatible trials) that was, however, in terms of the effect size, smaller than flanker effects reported in previous studies.
